The article states that a psi of only .25 is needed to get these results.
How much power would be needed to produce .25 psi ?
Probably 99.7% of the world thinks that cars look 'ugly' or 'odd' with a boat tail. People don't want a big thing sticking out the back side of their SUV. I see this invention as a way of catering to the rest of the world.
Besides, as pointed out in another thread, one of the reason big rigs don't have boat tails is that they have length restrictions.
This invention solves that problem.
